Orb of Discord

Indestructible, Hexproof
When Orb of Discord enters the battlefield or
the creature it was attached to would die, attach it
to another target creature an opponent controls.
If enchanted creature would take damage, it is
dealt double that damage instead. At the
beginning of your upkeep, put 1 ultimate counter
onto a Zenyatta, Propogator of Peace you control.
If you do not control a creature named Zenyatta, Propogator of Peace, sacrifice Orb of Discord.
